He's led TEN to the playoffs 6 times and has a .544 winning percentage. They had 3 years with 13 wins and another with 12. That's a decent track record.
However, I am not so sure he is in a good situation and it might be best for the organization to move on. That might get the Titans out of the duldrums. And another franchise would likely snatch him up right away, as he would be a better option than what they had at headcoach. Bill Parcells was a coach that was usually a better coach than the guy that replaced him, but he moved around all the time. Getting fired or switching teams doesn't mean someone is a bad coach, and keeping the same coach for years doesn't always mean that's best for the team either.
I think it would be best for him and for the Titans if they part ways.However, consider:
-- they have 6 game losing streaks in back to back years
-- they have had at least a 5 game losing streak in 5 of the last 7 years
-- much of their problem has been personnel related...and Fisher has final say over the 53
-- they've not won a playoff game since 2003
-- except for the Super Bowl season, they've only been better than 1 and out in ANY playoff year.
and likely they go to another SB the season they went 13-3 ( 2008), if not for a costly fumble by A. Cumpler at the 7 yard line with 9 mins remaining that would have given the Titans the lead, 14-13..they have one of the cheapest owners in the NFL, they didn't pay Haynesworth who was the centerpeice of their defense,
they have no name WR's and ho-hum players at key positions ( Kerry Collins, N. Washington, Britt)
Fisher has had very little to work with, and has coached in the AFC South, a div dominated by Manning's all-time great seasons over the past 5-7 years....
put Fisher on a team that has at least
some talent, and he'll be a lights-out coach...imagine Fisher coaching the Raiders..wow..improving defense, road-grader offensive line, explosive RB in McFadden and Bush, speed to kill at the WR position..
